How to Change FLV to MP4

Even though HTML5 is gradually replacing FLV (Flash Video) as the standard for streaming media over the Internet, FLV is still used by over one billion people worldwide for embedded video and on social networks such as Facebook or YouTube. However, to be played on a PC or Mac, FLV requires that you install additional codecs, and many mobile devices don't support this format at all. So if you want to watch a video you've downloaded from the Web on your computer or mobile device, make sure to convert the video to a more universal format such as MP4 or MPEG-4. Movavi Video Converter will help you get this done in no time.

To convert FLV to MP4 using Movavi Video Converter, download the program for Windows or Mac and follow the five easy steps below.

Install the FLV-to-MP4 Converter on Your Computer

Download and run the installation file for Movavi Video Converter. Follow the instructions on the screen to install the program.

Add the Video Files You Want to Convert

To add video files for conversion, click the Add Media button in the upper left corner of the interface, then choose Add Video, and select the files you want to convert.

Edit the Uploaded Files (Optional)

Before conversion, you can make changes in the files you’ve added via the built-in editing tool. To access it, click the Edit button in the file description.

Among the tabs in the new window, choose Stabilization to reduce shakiness in your videos. Choose Audio to reduce background noise or otherwise alter the sound volume in the files. Open the tab Adjustments to change the parameters of brightness, saturation, contrast, and others. Choose from a library of creative filters in the Effects tab and apply them to your clips. In the tabs Subtitles and Watermark, you can insert upload subtitles or add a watermark, respectively. Choose either Trim, Crop, or Rotate to get rid of unwanted details, cut away the edges of your videos, or rotate the footage.

Compress the FLV Files (Optional)

You can reduce the size of particular large files by using the converter. Click the file size value in the description section. In the box that opens, select the desired quality, bitrate, and size values. Click the Convert Sample button to convert a small fragment of your file and check out the quality.

Set MP4 as the Output Format

Click the Video tab. Choose the MP4 preset group, then the appropriate preset. If you want to transform FLV into MP4 for compatibility with your mobile device, click the Devices tab and then locate your device model.

Start Converting FLV Files to MP4

Converted files are saved to the Movavi Library folder by default. To change the output folder, click the Folder icon. After you have specified all the required settings, click Convert and wait for the conversion to be completed.

Upload Video to Your Mobile Device

The folder with converted files will automatically open as soon as conversion is finished. Now you can transfer the converted files to your mobile device. Turn on the device and attach it to your computer. Launch the uploading software on your device and follow the instructions or, depending on the device, transfer files to the target folder.
